[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] Embodiment

[0022] As Figure 1 and Figure 2 shown, the dental valve includes a dental valve body 1. One end of the dental valve body 1 is fixedly connected with a transition box 2. A filtering mechanism is arranged inside the transition box 2. The filtering mechanism includes an installation cylinder 4. The diameter of the installation cylinder 4 is the same as the diameter of the pipe orifice of the dental valve body 1. The inner wall of the installation cylinder 4 is clamped with a first filter screen 6 and a second filter screen 9. The diameter of the filter holes of the first filter screen 6 is larger than the diameter of the filter holes of the second filter screen 9. The first filter screen 6 is installed on the side facing the fluid, and the outer wall is fixedly connected with a lifting plate 3. Unlocking components for releasing the clamping of the first filter screen 6 and the second filter screen 9 are installed on both sides of the lifting plate 3, and the lifting plate 3 is connected to the transition box 2 through a fixing member, and the fixing member adopts a bolt.

[0023] Specifically, the fluid will first flow through the first filter screen 6, and the first filter screen 6 will intercept the foreign matters in the fluid. The foreign matters that cannot be intercepted by the first filter screen 6 will be intercepted twice by the second filter screen 9.

[0024] As shown Figure 1 in the figure, a seal is provided between the transition box 2 and the lifting plate 3. The seal is an O-ring, which is used to prevent fluid from flowing out through the gap between the transition box 2 and the lifting plate 3.

[0025] As shown Figure 2 and Figure 3 in the figure, a plurality of flow covers 8 are fixedly installed on the first filter screen 6, and the flow covers 8 are funnel-shaped.

[0026] Specifically, the fluid will flush the foreign matter into the interior of the installation cylinder 4 through the flow cover 8, and the second filter screen 9 will intercept it therein. At the same time, because the flow cover 8 is funnel-shaped, when the fluid backflows, the foreign matter between the first filter screen 6 and the second filter screen 9 will not be washed out, thus facilitating centralized treatment and avoiding contaminating the fluid.

[0027] As shown Figure 3 in the figure, the frames 7 of the first filter screen 6 and the second filter screen 9 are both provided with card slots, and the installation cylinder 4 is provided with a movable slot 41. A steel ball 5 is connected to the interior of the movable slot 41 through a first elastic member. The first elastic member is a V-shaped spring leaf, which is used to prevent the steel ball 5 from disengaging from the movable slot 41. The steel ball 5 is adapted to the card slot.

[0028] Specifically, when the steel ball 5 is located between the movable slot 41 and the card slot, the first filter screen 6 and the second filter screen 9 cannot be taken out from the installation cylinder 4. After the steel ball 5 completely disengages from the card slot and enters the interior of the movable slot 41, the first filter screen 6 and the second filter screen 9 can be taken out from the interior of the lifting plate 3 to clean the foreign matter attached thereto, which is convenient for repeated use.

[0029] As shown Figure 2 and Figure 3 in the figure, the unlocking assembly includes a push plate 10. Magnets 11 and guiding sliders are respectively fixedly connected to both sides of the push plate 10. A guiding chute 31 is provided on the side wall of the lifting plate 3, and the guiding slider is slidably connected to the guiding chute 31. The magnet 11 is located on one side of the steel ball 5.

[0030] As shown Figure 2 in the figure, a second elastic member is fixedly connected to one side of the guiding slider. The second elastic member is a spring, which is used to push the push plate 10 and the magnet 11 away from the installation cylinder 4. The end of the second elastic member away from the guiding slider is fixedly connected to the side wall of the guiding chute 31.

[0031] Specifically, when it is necessary to take out the first filter screen 6 and the second filter screen 9 from the inside of the installation cylinder 4, it is necessary to simultaneously press the push plates 10 on both sides of the lifting plate 3 until the magnet 11 is attached to the outer wall of the installation cylinder 4. At this time, the steel balls 5 will be completely sucked into the inside of the movable groove 41 by the suction force of the magnet 11. At this time, the first filter screen 6 and the second filter screen 9 can be taken out from the inside of the lifting plate 3, and the foreign matters attached thereto can be cleaned for repeated use. After the push plates 10 are released, the push plates 10 and the magnet 11 will be pushed away from the installation cylinder 4 by the acting force of the second elastic member. At this time, the steel balls 5 will be out of the magnetic attraction range of the magnet 11 and fall back to the end of the movable groove 41 again. When the steel balls 5 are located between the movable groove 41 and the card slot, the first filter screen 6 and the second filter screen 9 cannot be taken out from the installation cylinder 4.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
